Reloading a window apprently clears Java project settings due to different workspace storage chosen

Environment

• Operating System: macOS (local host) + Linux (SSH remote host)
• JDK version: 17.0.9
• Visual Studio Code version: 1.89.1
• Java extension version: 1.31.0

Steps To Reproduce

1. Open a large Java project on a remote machine with SSH remote development
2. Configure the Java project, e.g. add some source paths
3. Reload the window

Current Result

Configuration added in the step 2 is apparently lost.

Expected Result

Configuration added in the step 2 is kept.

Additional Informations

I found that the -data directory passed to jdt.ls differs before/after the reload.

• Before: -data /usr/local/google/home/nya/.vscode-server/data/User/workspaceStorage/4f53a3d603ab9ba87f981c0821b0dc62/redhat.java/jdt_ws
• After: -data /usr/local/google/home/nya/.vscode-server/data/User/workspaceStorage/4f53a3d603ab9ba87f981c0821b0dc62-1/redhat.java/jdt_ws

Notice the -1 suffix added to the workspace storage directory.

In fact, a VSCode extension may receive different context.storageUri for the identical workspace when multiple instances of VSCode opens the workspace concurrently (c.f. https://github.com/microsoft/vscode/issues/128234). This can happen even on a window reload because a storage directory lock is released only on the VSCode process exit (https://github.com/microsoft/vscode/blob/5f646b8e67a869ef33061085ffe0e377d5ba040c/src/vs/workbench/api/node/extHostStoragePaths.ts#L52).

I guess this problem happens only in remote development because VSCode skips obtaining locks for local extension hosts (https://github.com/microsoft/vscode/issues/128528).

Start by reproducing the remote SSH reload flow and compare the extension's context.storageUri with the jdt.ls -data path before and after reload. Review the referenced VS Code extHostStoragePaths.ts behavior and the extension's jdt.ls launch handling. Done means Java project settings remain available after reload instead of moving to a -1 workspace storage directory.
